Question

Hint:

### We are given the value of u. We have to find the value of the equation for given value of u. We will first find the degree of the equation. Then, we will solve the given equation.

## The correct answer is:

### The given value of u is as follows:

We have to find the value of

We will simplify u before solving it further.

Let z = tanu

Here, z = f(u)

So,

The degree of function is 2.

When z = f(u)

g'(u) = 2cos2u

The solution will be

The option which is "(2cos2u - 1)sin2u", is the right option.

We need to remember different formulas for this type of questions.
